Mobile version of Confluence on iOS 10 Safari serves up invalid login screen

Summary

When accessing Confluence from a mobile device, the application serves up a login screen that is invalid. This is true for all pages, even with anonymous access enabled.

Steps to Reproduce

1. Install Confluence 5.10.4 (this can also be replicated in previous versions of Confluence such as 5.9.10)
2. Enable anonymous access
3. Make sure the system add-on called the 'Confluence Mobile Plugin' is enabled
4. Access the Confluence instance using iOS 10 and the vanilla Safari browser that comes included
5. Notice you will get an invalid login prompt asking you to login to Confluence

Expected Results

Confluence mobile should open up Confluence without asking you to log in.

Actual Results

A prompt comes up in Confluence asking all users to log in every few seconds.

Notes

This prompt only happens in Safari that comes bundled with iOS 10 and no other mobile browsers tested.

Workaround

-Switch from Confluence Mobile view by clicking the "Switch to desktop version"
-Disable Confluence Mobile by disabling the system add-on called the 'Confluence Mobile Plugin' . Please note CONF-40782 - "Disabling the Confluence Mobile Plugin also disables the Workbox - Host Plugin in Confluence 5.9.X" when performing this workaround.
